DYEING- APPARATUS.

Application filed June 20, 1923. Serial No. 646,588.

The present invention relates to machines for dyeing, washing and rinsing fabrics and other materials, particularly garments, hosiery, hats and other wearing apparel, also thread and yarn.

The object of the present invention is to produce a machine in which a number of different articles, or batches of articles, may be kept separated and treated at the same time, and in which the dye liquid is circulated through the articles, the liquid being so directed that it will keep the articles from clinging together and thus secure uniform results.

The invention is illustrated'in the accompanying drawings, in which Figure 1 is a sectional end view through a a storage and mixing tank and an associated cular wall provided with a door 13.

dyeing machine.

Figure 2 is a vertical sectional view on the line 22 of Figure 1.

Referring to the drawing, A indicates a storage and mixing tank in which the dye may be mixed and heated before passing to the dyeing machine and B indicates the dyeing machine proper. The tank A may be of wood or metal, and the tank B is preferably constructed of sheet metal.

lVithin the tank B is a cylinder 10 having perforated cylindrical end walls. The cylinder is provided with radial partitions 11 which divide it into compartments 12, and each compartment has an opening in its e radial walls 11 preferably terminate in an inner cylinder 14 whereby acute angles at the bottoms of the compartments are avoided. The cylinder is mounted on a shaft 15 which in turn is mounted in suitable bearings 16 on the ends of the tank B and provided with a suitable pulley or gear 17 by means of which the cylinder can be slowly rotated.

The tank B is provided with a lid or cover 18 and with an over-flow pipe 19 through which dye liquid is returned to the tank A. The dye tub or tank may also be provided with an. air vent 20. Steam may be conducted into the tank A through a pipe 21 to keep the dye liquid at a proper temperature.

In the operation of the machine, the dye liquid is continuously circulated from the tank A to the tank Band returned to the tank A, this being accomplished by a suitable piping and a pump 22. The pump takes liquid from the tank A through the pipe 23 and delivers it through pipe 2 1 and through a series of nozzles into the bottom and ends of the tank B. As shown, the pipe 24 extends along under the bottom of the tank B in a central position and it is provided with a series of branches or nozzles 25 through which the liquid is directed vertically upward under the middle of the cylinder. The currents of liquid from the nozzles 25 strike the perforated outer wall of the cylinder and cause upward currents in the several compartments as they pass over the nozzles, thus circulating the dye liquid through the articles under treatment and keeping them from accumulating in masses which would prevent proper dyeing.

I'also preferably provide the pipe 24 with upwardly directed branches 26 at the ends of the tank B, these branches being provided with nozzles 27 through which the liquid is forced against the perforated ends of the rotating cylinder, part of the liquid passing through the perforations and assisting in circulating the fluid therein.

It will beevident that the structure described is simple and inexpensive and that in opeation it will accomplish the purposes set forth, that is, it will continuously supply dye liquid to the tub or tank B and keep the articles being dyed in suspension and agitation, whereby uniform results are obtained. The dye may be drawn off and other dye substituted, or water for washing purposes may be injected into the tank B by suitable piping and valves, which it is not necessary to describe, as such arrangements are well known.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

1. In a dyeing apparatus, the combination with a storage tank, of a dyeing tank, a horizontal, rotatable cylinder in said dyeing tank having a perforated cylindrical wall spaced slightly above the bottom of said dyeing tank, means for circulating dye liquor from the storage tank into the bottom of the dyeing tank so that it impinges against the cylinder and passes through the perforations therein to agitate the material being dyed in said cylinder, and an overflow adjacent the top of said dyeing tank for conducting the dye liquor back to said storage tank.

2. In a dyeing apparatus, the combination with a storage tank, of a dyeing tank, a 1'0- series of inlets in each end of the dyeing tatable cylinder-in said dyeing tank, said tank, and means for directing dye liquor cylinder being provided With, radial partifrom the storage tank through said inlets 10 tions dividing it into compartments andhavagainst the bottom and sides of said cylinder.

' ing a perforated cylindrical wall and,.per- In testimony whereof I hereunto afiix my t'orated ends, a series of inlets in the bottom signature. of the tank beneath said cylinder,- aiseeond- FRANCIS C. W. STELTER.
